Need a Tool for Javahelp

I am supposed to provide a full-featured help component for a project whose interface is Swing-base. My search led me toward Javahelp which is a very complete framework for providing help. But as I read its documentation and tried to develop some sample Help projects by that, I found it cumbersome to complete its necessary XML files (such as Index and Content).I am looking for a free tool to provide a simple Grapgical interface to create Javahelp projects. I found some but most of them are commercial and none-free.I would be grateful if anyone could help me by introducing a Free Tool to help me develop a large Help project in a timely manner.
